After creating a new topic I was trying to play with the new Clojure client. I was typing the code from the example into the repl, so perhaps I made an error, but it looks like an SSL issue

[lbradstreet]

Thanks for the report. I believe this is due to the local certificate store not including the letsencrypt root certificate. We'll discuss a fix and will get back to you.

[MichaelDrogalis]

Thanks for the report @reilly3000!

As @lbradstreet suspected, it looks like this is due your JDK version not having the root certificate for our provider. LetsEncrypt was included at least after Oracle JDK version 8u101. It was also later added to 7u111.

At the moment, I'm on:

michaels-mbp-4:pyroclast-clojure michael$ java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

And it seems to work okay. This issue is discussed here also. All you should have to do is upgrade your JDK version. In the mean time, we're going to get another SSL cert so no one else runs into this issue. Sorry for the road bump!

[reilly3000]

Updating to 8u131 got me running just fine. On my mac my JRE was up to date but my JDK was woefully old...

[lbradstreet]

@reilly3000 great to hear. Thanks for the update.
